The HI6850 is Hardy Process Solutions' advanced multi-channel weight controller, designed for industrial weighing applications that need more than one scale in a single instrument — filling, checkweighing, rate monitoring, and belt scale control across up to four independent channels. The main channel delivers 250 Hz processed weight updates through a 24-bit ADC, while three optional channels each run at 100 Hz. A dual-core processor separates measurement from communication, so fieldbus traffic never delays weight data.

How does the HI6850 connect to plant control systems?

Dual-port Ethernet with an embedded switch carries EtherNet/IP and Modbus TCP as standard — no separate gateway modules needed. An optional PROFINET card slots into the modular expansion bay. On the I/O side, two expansion card slots accept GPIO cards (analog 4–20 mA in/out plus digital I/O), 8-channel DC relay cards, or a second high-speed scale input card. For legacy integration, the controller also supports 4–20 mA analog outputs for weight retransmission to PLCs and DCS.

What makes the HI6850 suitable for filling and batching?

Hardy's WAVERSAVER+ adaptive filter rejects mechanical vibration from nearby conveyors, mixers, and filling heads without slowing the measurement — configurable from 0.25 to 7.5 Hz. C2 electronic calibration eliminates test-weight calibration runs by storing load cell performance data digitally. Setpoint-based weight control supports loss-in-weight, gain-in-weight, and rate-of-change applications, with high-speed digital outputs for direct valve and feeder actuation.
